The correct answer is "Random Variable". A random variable is a variable that takes on numerical values that are determined by the outcome of a statistical experiment. In other words, a random variable is a numerical representation of the outcomes of a random process. Random variables can be discrete or continuous, depending on whether they take on a countable or uncountable number of values, respectively. They are a fundamental concept in probability theory and statistics and are used to model a wide range of phenomena in many fields, including economics, engineering, and biology.
